We Do Make ‘Em Like They Used To!


The story began with RCA* when Harry F. Olson developed the 44 and 77 series of ribbon microphones. Jon R. Sank succeeded Mr. Olson and was challenged by RCA to improve upon Harry’s best microphones. He did just that with the BK11, a direct descendant of the 44 series. It has been an industry secret for many years among top engineers, that the BK-11 is the most advanced ribbon microphone in the world.


Beginning at just 10 years old, Stephen Sank studied with his father and began building upon lessons learned from the original RCA laboratory. Jon Sank shared more than 50 years of skill and innovation with his son Stephen before passing away in 1998.

Today, Stephen continues the Sank family tradition of developing quality hand crafted ribbon microphones in collaboration with Cloud Microphones. The Cloud JRS-34 takes the next step in the legendary BK-11 and 44 series of ribbon microphones.
